Empower yourself with DIY video surveillance
Computer vision provides the functions for recognizing and identifying an image as a specific object, such as a house, a human, or a road. Human beings recognize an object using their knowledge of the object (e.g., a house, a human, or a road). It is allow to develop image-recognition technology that can recognize all kinds of objects.
The NVR eliminates these problems, because it is instead connected directly to a network. IP cameras that are connected to the same network, usually by way of a PoE switch, are then able to transmit footage to the NVR. Systems based around an NVR are much easier to scale up than DVR systems, simply because they can accept a new camera once it is added to the network. In the worst case, all that would be required is an additional PoE switch. Some IP cameras are also wireless and can transmit footage to the NVR over Wi-Fi.
